Description
Technical Field
The invention relates to the field of hydraulic valves, in particular to a 1D cavity type multifunctional intelligent control rotary valve functional module unit.
Background
Valve products are widely used in fluid control in various technical fields, and a two-position two-way valve is the most common one. The common two-position two-way valves in the market at present adopt a slide valve structure or a cone valve structure driven by an electromagnet. The patent application number 90223667.9 discloses a two-position three-way and two-position two-way valve, which comprises a top rod, a valve body, a valve core spring, an end plug, a sealing ring and the like. The two-position two-way valve has the common problems of small flow, single function, large vibration during transposition and difficult realization of digital control, and has the advantage of convenient combination of the two-position two-way valve and the multi-way valve.
The chinese patent with patent application number 201110025024.9 discloses a high-frequency hydraulic rotary valve, which comprises a valve body, a valve core, a valve sleeve, a transmission shaft and other parts. The valve core is provided with five sections of complete cylindrical surfaces which form clearance seal with the valve hole to divide the valve into four sealing sections. The first sealing section is functionally equivalent to a conventional two-position four-way reversing valve, and the second to fourth sealing sections form a two-position four-way reversing valve with a straight-through left position and an M-type sliding valve function right position. The valve core is driven by the control motor to rotate at a high speed to realize high-frequency switching of an oil way, but the five-section type valve core has large load torque, large accumulated errors of machining and assembling, influence on control precision and frequency response and complex machining process.
In the early twentieth century, people have adopted the modular concept to improve the efficiency, consistency and reliability of production in the application of the building industry. With the continuous development of the technology, more and more fields adopt the modularization concept to design and produce products. Modular technology is created by the need for product serialization, combinationization, generalization, and standardization. The purpose of serialization is to meet the requirements of demand parties on products to the maximum extent and economically and reasonably by using products with limited varieties and specifications. The combination is a special product formed by combining a plurality of general series components and a small number of special components and parts. The generalization and standardization is to use mature parts of the original product, which not only can shorten the design period and reduce the cost, but also can increase the quality reliability of the product. Therefore, the platformized and modularized product is an effective method for solving the contradiction between customized production and batch production.
Chinese patent application No. 201510260021.1 discloses a modular valve system including a valve body including at least four ports for fluid flow direction switching or fluid mixing and at least two valve spools insertable into the valve body, each valve spool having at least one linear actuator and an axial sealing member. Each axial sealing element is used to open or close a corresponding two ports. The modular valve system can be expanded to a larger number of ports, the ports can be switched between an inlet port and an outlet port, but the valve core of the modular valve system is driven by a linear driver instead of a rotary driver, so that the modular valve system only can play a role of a switching valve and cannot play a role of a regulating valve.
A two-position two-way valve is used as a functional module unit and is applied to the control of a traditional hydraulic circuit to realize the functions of opening, closing and adjusting, and no relevant report is found at present.
